Complexation of cyclodextrins with anion constituents of antigenic determinants in water (axial complexes) and in N,N-dimethylformamide (equatorial complexes). A thermodynamic study
Abstract
The first set of thermodynamic data on the complexation of cyclodextrins with anion constituents of antigenic determinants (4′-hydroxyazobenzene-3- and -4-carboxylate) and on the transfer of α- and γ-cyclodextrins in the water-N,N-dimethylformamide solvent system are reported; the data suggest the formation of axial or inclusion complexes in water and equatorial or lid type complexes in N,N-dimethylformamide.
